It saved us from getting hopelessly lost in the maze of city streets.
Fuses are designed to protect your car's electrical system from overloads. When too much current flows through a circuit, the fuse blows, breaking the connection and preventing damage to more expensive components. Locate your car's fuse box, usually under the dashboard or in the engine compartment. Consult your owner's manual to identify the fuse specifically designated for the cigarette lighter. It's often labeled as "CIG," "ACC," or "PWR OUTLET." Once you've found it, visually inspect the fuse. If the thin wire inside is broken or blackened, the fuse is blown and needs replacing. Use a fuse puller (often found in the fuse box) to remove the old fuse and replace it with a new one of the same amperage. Make sure you get the right amperage; using a higher amperage fuse can be dangerous. You can usually pick up a fuse assortment pack at any auto parts store for a reasonable price. After replacing the fuse, test the cigarette lighter with a known-good device. If it works, congratulations! You've likely solved the problem. If it still doesn't work, move on to the next step.
Inspecting the Connection: Is it Loose?
Sometimes, the problem isn't a blown fuse but a loose or corroded connection. What exactly does it mean to inspect the connection and why is it important to do? It’s important to inspect the connection because that could be causing the lack of power to the outlet. A loose connection can prevent proper electrical contact, while corrosion can build up over time, hindering the flow of electricity.
